Abstract

PURPOSE:To enable to increase the line efficiency and to shorten the transmission time, by transmitting the preceding data block first at transmission, transmitting the line occupancy request start information next, and transmitting the data of the latter half as a result of priority control. CONSTITUTION:A station ST2 obtaining the transmission right with the line occupancy station selective information SEL from a communication stations ST1 transmits the first half of the data information block as DATAU. Succeedingly, the station ST2 transmits the line occupancy request start information POL, and as a result of priority control, after the time for the length of the line occupancy request information RESP transmitted from the transmission request station is elapsed, the latter half of the data information block is transmitted as DATAL. Thus, the line efficiency is kept high and the transmission time can be shortened.
